Abstract
A video processing system comprises an analogue to digital converter for receiving a video signal and converting the signal into digital form. A digital frame store receives and stores the converted video data. Store addressing means address locations within the frame store to write in and read out data therefrom. A digital to analogue converter receives the data read out from the frame store and converts the data into analogue form and accessing means provides random access to the frame store locations during the video blanking time to allow processing of the data with an algorithm.
